Pete,

Not a problem at all... Glad to help out!

The camshaft information that I have is as follows:

#3925535 (First Design L-88)

VALVE LIFT

Intake - .540" (includes lash - .022")
Exhaust - .560" (includes lash - .024")

VALVE TIMING

Intake
Opens (BTC) 55
Closes (ABC) 102
Duration 337

Exhaust
Opens (BBC) 98
Closes (ATC) 68
Duration 340

#3959180 (Second Design L-88/ZL-1)

VALVE LIFT

Intake - .560" (includes lash - .024")
Exhaust - .600" (includes lash - .026")

VALVE TIMING

Intake
Opens (BTC) 62
Closes (ABC) 105
Duration 347

Exhaust
Opens (BBC) 106
Closes (ATC) 73
Duration 359

As noted above, the lift figures include valve lash and the opening and closing points are measured (I believe) .004" off the base circle.

Still working on that magazine article...

Regards,

Stan
